Patent GB-190403891-A (GB)
Title: Improvements in, and relating to, Electrical Energy Meters
Inventor: ARNO RICCARDO
Filed: 1904-02-16
Granted: 1904-12-22
Abstract: 3891. Lake, H. H., [Arno, R.]. Feb. 16. Energy meters.- A rotary field induction motor meter, having a main - current coil SA, is provided with a pair of auxiliary coils Sc<1>, Sc<11> producing a resultant magnetic flux in phase with the electric pressure between the supply mains a, b, to compensate for friction, by co-operation with the main pressure coil Sv of the meter, without the use of an unsymmetrical arrangement. One auxiliary coil Sc<1> is in series with the pressure coil SV, and the other SC<11> is in series with a large inductance L, between the mains a, b ; these pressure circuits are made to have equal impedances, and the connections are such that the equal currents thus obtained flow oppositely through the two auxiliary coils. The auxiliary coils are adjustable relatively to the rotor of the meter. When the current in the main pressure coils Sv is nearly in quadrature to the applied pressure, the inductance coil L has an iron core with open magnetic circuit, so that the current in the coil L lags considerably less than 90‹ ; if the meter is to be used only on non- inductive loads, the current in the main pressure coils SV may lag less than 90‹, and the inductance coil L then has an iron core with closed magnetic circuit, so that the current in the coil L is nearly in quadrature to the applied pressure.

Granted: 1904-05-12
Abstract: 5740. Stoney, T. B. March 9. Tidal energy, utilizing. - Consists in utilizing the rise and fall of the tide to work pumps which raise water to a high level reservoir or land, from which the water flows to drive dynamos. Fig. 1 shows a plan of the arrangement. When the tide has risen a certain amount, water is allowed to flow into the low-level reservoir E past pump turbines arranged in the chamber C, which raise water to the reservoir K. When the tide is high, the reservoir E is full, and, when during the ebb it reaches a certain point, the water is allowed to escape from the chamber E and operate the pumps. The water in the reservoir K flows to the dynamo turbines by the channel L and thence into the reservoir E.

Title: Improvements in Incandescent Gas Lamps.
Inventor: FARKAS ARMAND
Filed: 1904-05-28
Granted: 1904-11-10
Abstract: 12,155. Farkas, A. June 9, A.D. 1903, [date applied for under Patents Act, A.D. 1901]. Railway-carriage roof and like lamps.-In an incandescent gas lamp particularly for railway and other carriages, the injector and bunsen tube are surrounded by an ejector cone e to protect them from the hot gases. Above the cone, the bunsen tube is surrounded by a conical jacket f, outside which is another jacket g, the two jackets forming a passage through which the hot gases pass to the chimney v, the lower edge of which comes near or surrounds the upper edge of the jacket g. Air enters through the gallery x and passes through holes in the cap n into the casing a. Part of the air passes to the bunsen tube through radial tubes h extending between the jackets f, g, and the rest passes through holes r in the reflector q into the globe w. When the curtains are drawn over the lamp, the gas is turned off, leaving only a small bye-pass jet burning. Where the burner can only be got at from the top, and is carried by a branch b connected to a joint c, a small pipe i is connected to the casing of the joint and extends along the branch and terminates near the mantle after passing through the stopcock d. The joint c is connected directly by a small passage to the supply pipe l and also by a passage in which is interposed a valve s. When the curtains are drawn over the lamp, the curtain rods p actuate levers o which allow the valve s to be operated by its spring to close the passage, the main flame being thus extinguished, and only a small jet left burning. In lamps in which the globe is hinged to allow access to the lamp from below, the cock is fixed, and the plug of the cock d may be operated by a rod from the outside and acting either independently of or concurrently with the curtains for enclosing the globe. The plug is also designed to admit gas continuously to the pipe i of the bye-pass.

Abstract: 13,102. Bradshaw, R. June 24. Automatic instruments; organs, harmoniums, and like instruments.- In order to adapt pneumatic piano - players for use with organs, the treadles of the apparatus are e coupled t o those of the organ, and special valves are provided i n both to permit of sufficiently rapid action of the treadles to suit the varying requirements of each. A spring valve is arranged on the suction or reservoir bellows of the pneumatic appa - ratus to allow the entrance of sufficient air to permit the treadles to move with the requisite freedom when the wind consumption in the organ is the greater. This valve consists of a metal plate d, Fig. 1, inside the bellows, mounted on a stem e with a spring f. When the apparatus is used with a piano, this valve is locked in the closed position by a crank h, actuated by strings attached to a cross-bar k ; otherwise the crank is held off by a spring j. A slide valve q, Fig. 2, with a spring s is placed on the wind-chest of the organ beneath a bar u, and is controlled by hand through a string x to suit the loudness of tone required and also the varying wind consumption of the instrument. In rewinding the music sheet, this valve is fully opened, thereby permitting the treadles to move quite freely. The treadles are coupled by means of cords passing from their upper ends round pulleys at the base of the apparatus and the instrument, and along the floor. As the keyboards, of organs are usually higher than those of pianofortes, an intermediate keyboard with an upper and a lower row of keys is fitted to the organ and the apparatus is applied to the lower row. These keys consist of thin flat metal bars, pivoted in slots in a couple of long wooden bars placed across the keys of the organ. The inner ends of the bars are connected by vertical links, and their outer ends are provided with fingers of wood and felt.
